A final resolution
This is an updated review. Originally I gave it 1 star and slammed them, as their agent promised a full refund (as within 2 days I realised it was not suited to what I needed), then didn't deliver. HOWEVER - a higher ranking aagent called David got back in touch with me, appologising because he saw the other agent had promised this - and done nothing for two or more weeks ! - David has given me a full refund. So absolute praise for him, as he has redeemed the name of CleverFiles or Disk drill. I would have given 5 stars but the laise-fair - nonechalant attitude of all the other agents who dealt with my request before him, would make it undeserved. Maybe I should have only given 3 stars - but the 4 is due to this one excellent agent, David.
